Press in factory 911 wheel studs on 996 turbo??
I have seen and spoken to a few people that swear by the factory 911 aircooled press in studs as opposed to the thread in. I am currently running the rennline which seem okay, but I have read about some breaking on the track. Thoughts or experiences??

Studs are consumables. They break. Rears need replacing almost yearly. I broke 4 in turn 12 at Road Atlanta. Literally 1 stud kept me from a very bad crash. On flat tracks its not as bad, but ones with high compressive forces like Road Atlanta will eat them up. A friend of mine has a GT3 R and had a wheel come off. Same track. I don't remember the brand but they are the best around and still break. I did have some from a boxster racing place in Cali that lasted longer, can't remember names at this point but they installed with an Allen wrench on the flat end. If you run compressive tracks, have good amounts of downforce and run Hoosiers DOT or better, replace rears yearly. Cheap insurance. Fronts should last 2-3 seasons of track days.

Stop reading negative threads on the internet. Sure if racing (and mayyyyybe the street) they are consumables, but they're not snapping like twigs here. I've used em for many, many years w/out issue. My P car ones been on for years untouched in great shape.

Never had a problem with lug bolts though. Just studs. Can't blame Porsche.

But there's many who run screw in studs w/out issues. Only people come here to complain, no one is gonna write, hey my studs still working as intended! Think about it. I wouldn't worry about them failing. Inspect them often. Change as maintenance if so desired. I don't see a need to go to a press in stud.

Based on the original post, concerning track, most everyone who runs them on track car regularly replaces them regularly. I'm just here to answer a question that was posed. Broken studs can be a very costly mistake. If you are on street tires in a novice group, or mostly street driving, it's not nearly as big of an issue. But if you track on sticky tires in advanced groups, they are going to break. Period.
They are inexpensive and easy to replace. They don't need advocacy. They are wheel studs, a basic replacement part.

Personally I keep lugs with me at all times just in case. It's pretty easy to extract a broken stud and save your weekend. I almost quit the studs altogether after the near incident. I wouldnt trust anything to last forever. Press In seems like a harder to replace item should you be at the track and maybe one fails. Nothing is invincible.

Cause all things considered a part clamped on is better than a part bolted on, at least IMO.

This is an interesting issue to me. I have a moderately modded car and run DOT tires w/ the stock bolts on track When teching/ classing my car for pca events they insist if I add a few more performance modifications I will have to run studs with open end lug nuts. Why? Are they considered stronger, safer?

You can replace them at regular intervals or be hard headed and hate yourself when they snap on you. They are fairly cheap and take a hr or two to replace. Is it really worth the risk........no.
